PROCESS OF ATTACHING SHOE WELIS AND OUTER SOLES Filed Sept. 12, 1928 Inventor W Sijfz' Attornqy Patented Mar. 11, 1930 UNITED STATES WALTER S. KING, OF LAKELA-ND, FLORIDA PROCESS OF ATTACI'IING SHOE WELTS AND OUTER SOLES Application filed September 12, 1928.

This invention relates to new and useful improvements in shoes and the same resides more particularly in a novel process by which shoe welts may be attached in the construction of shoes in a more stable and durable manner.

The present practice in the shoe manufacturing industry is to dispose the edge portions of the shoe upper inwardly and in this position the welt is attached thereto.

This manner of attaching the welt, although generally accepted to be practical nevertheless has certain disadvantages which this invention contemplates to overcome.

As a result of the conventional method above stated, a cavity is created within the shoe which is generally filled by some cement deposit. This cement, especially in warm weather, becomes soft and bulges in various places, with the result that when the same again becomes solidified, the wearing of a shoe thus distorted causes extreme discomfort and is pernicious to the feet of the wearer.

The prime object of this invention is to obviate the necessity of filling in the cavity caused by the disposition of the welt, by attaching the welt to the shoe part in a new and advantageous manner.

Another important object of the invention resides in a method of attaching welts wherein the possibility of the welts pulling loose is reduced to a minimum.

After reading the following specification and claim, other important objects and advantages of the invention will become apparent.

In the drawings:

Figure 1 is a fragmentary transverse sectional view through one edge portion of the shoe upper showing the first step in the novel method.

Figure 2 is a similar View of the shoe upper showing the second step in the method, wherein the welt and edge portion of the shoe upper have been bent outwardly and secured at the bent portion to the inner sole.

Figure 3 represents a fragmentary transverse sectional view through the shoe upper, inner and outer soles, showing the third step in the method, wherein the lower edge portion Serial No. 305,487.

of the welt has been secured to the inner and outer soles.

Figure 4 is a view similar to that shown in Figure 3, wherein the top portion of the welt and the split edge portion of the outer sole are secured by stitching completely through the top portion of the welt, the outwardly disposed edge portion of the upper, the inner sole and the entire thickness of the outer sole, this being the fourth step of the process.

Figures 5, 6, and 7 represent respectively the usual thin welt, the medium welts, skived to a pointed edge, and a heavy welting split diagonally, the welt form being shown in. cross section.

Now referring to the drawings in detail, wherein like numerals designate like parts, the description will commence with the first step in the method. In this, the shoe upper 1 has its edge portion 2 primarily disposed outwardly in the manner shown clearly in Figure 1. This step also involves the bending of the welt 3 throughout its longitudinal intermediate portion to provide upper and lower edge portions 4 and 5 respectively.

The second step in the method is as: shown in Figure 2 of the drawings, and consists in disposing the inner sole 6, against the bottom of the outwardly disposed edge portion of the shoe upper 1. and stitching through the bent portion in connecting the welt and shoe upper to the inner sole.

The stitching is designated by the numeral 7. In Figure 3 of the drawings,thethirdstep in the production of the shoe by the present method consists in splitting the outer sole 8 inwardly at its lower edge portion and stitching the lower edge portion of the welt and inner sole to the upper portion of the outer sole at the split edge portion. This latter stitching is designated by the numeral 9.

The last step in the method consists in stitching the upper edge portion of the welt, the lower edge portion thereof, the edge por tion of the upper, the inner sole, and the entire thickness of the outer sole together in the manner shown in Fig. 1, wherein the stitching is designated by numeral 10.

It is to be understood that either of the forms of \velts shown in Figures 5, 6 and 7 respectively may be employed in the present method Without departing from the spirit and scope of the appended claim.

Having described the invention, what is claimed as new is:

A method of attaching shoe welts comprising disposing the edge portion of the shoe upper outwardly, securing a folded Welt strip at its longitudinal intermediate portion to the upper at its bent portion, disposing one edge portion of the Welt over the edge portion of the upper, applying the outer sole to the inner sole, securing the last mentioned portion of the welt With the edge portion of the upper to the inner sole and outer sole, then disposing the opposite edge portion of the Welt down against its secured portion, and securing the upper edge portion of the welt and the outer sole to the inner sole at the margin of the shoe upper.

In testimony whereof I aflix my signature.
